WINDING-MACHINE.

To all whom t may concern:

Be it known that I, CHARLES D. REYNOLDS,

a citizen of the United States, residing at` Cranston, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in VVinding-Machines, of which the following is a specification'. l

My invention relates to winding machines and consists of an improved clutch-mechanism for controlling the operation of-the winding-mandrel of the machine combined with means for securing the cop-tube or shell on the mandrel and for releasing it therefrom at the completion of the winding. The object of'my improvement is to simplify the mechanism of the machine by providing a single manually-operable means for operating both the cop-tube holder and its clutch-devices whereby the control of the machine is rendered more convenient and its operation more efficient.

The manner and means for carrying out the improvement are fully explained in the following speciication, illustrated by the accompanying drawings, in which like reference characters designate like partsA ln the drawings Figure 1 is a longitudinal, sectional view of the cop-tube holder or winding-mandrel shown in connection with its clutch-device and the means for manually operating the same;

Referring first to Fig. l, F designates a portion of the upright frame of the winding machine which is formed with a hub or bearing f for supporting the fixed spindle -S for the winding-mandrel H. Preferably the spindle S is constructed of hollow rod or tubing and its end is driven into a bore in the hub j with the greater portion of its length overhanging the side of the frame F. Mounted to rotate freely on the spindle S is a belt-pulley P arranged with its hub p abutting the end of the hub f. Abutting Specification of Letters Patent. Patented Mam. ft2, QS,

Application filed July 18, 1916. Serial N o. 109,878. v

the outer end of the hub p of the pulley P is a relatively long sleeve or bushing B also free to rotatey on the spindle S. The bushing B is held in place on the spindle S by means of a rod R extending through the bore s of the spindle. At its outer end the rod R is formed with, or has secured thereto a cap r iitted to the end of the bore s and provided with a head or flange 1 abutting the end of the bushing B. rlhe opposite end of the rod B is inserted through an axial hole in a cap R, fitted to the inner end of the spindle S, and secured in place by a nut r2. Preferably the cap R is drilled with an oil-hole r3 to provide for the introduction of lubricant into the bore of the spindle S which serves as an oil-chamber for distributing it through the openings s, s to the several rotating elements mounted on the spindle. Y

FiXedly mounted` on the outer end of the bushing B is the winding-mandrel or coptube holder H which as herein illustrated is made in the form of a truncated cone. to adapt it to receive the conicalvtubes or shells in common use for supporting cone-packages of yarn or thread. Between the cone-tube holder H and belt-pulley P is a clutch-'member C adapted to connect the holder to be driven from the pulley. rlhe cone-holder H is chambered or hollowed out at both ends, for the purpose of saving metal and weight, and is bored at L to receive the bushing B to which it is secured by a set-screw t, or through any other suitable means. rlhe rearward end of the solid portion of the holder H abuts the side of an annular flange or collar 5 on the bushing B, and held therebetween is a spider-like spring-member E preferably formed from flat steel. Referring to Figs. 4 and 5, the spring-member E is-constructed with a central, circular plate or ring e fitted over the bushing B and formed with four radial arms ve, e bent at an angleto adapt\them to it within the cored out cavit .h2 at the base end of the holder H. AdJacent the ends of each :zrni e are two triangularly-shaped projections e2, e2 bent up from their sides to form sharp prongs or teeth adapted to be forced into the paper or ber cone-tube X which fits over the outside of the holder H, see Fig. l. Referring particularly to Fig. 5, the rearward endof the shell of the holder H is cut away `or slotted longitudinally to provide four lugs or fingers h3 which are straddlecl project beyond the peripheral surface of the vio holder H, due to the spring-action of the arms e', thereby causing them to bite `into the inner surface of the cop-tube X. Referring to Fig. 4, the ends of the arms e extending rearwardly beyond the teeth e2 are bent down at anangle to provide the inclined fingers e3 for engagement with an interiorlybeveled face c2 of a ange con the hub c of the clutch-member C, see Fig. 2. Through this engagement the teeth or prongs e2 are adapted to be withdrawn from engagement with the interior of the cone-tube or shell X by the depression of the arms e when the clutch-member C is slid to the left as more fully explained hereinafter.

Referring to Figs. 1 and 2, the clutchmember C is of usual type formed with a tapered face ycadapted to frictionally engage the corresponding, interior, tapered face p of the pulley P. The hub c of the clutch-member C is fitted to slide. on the bushing B and extends to the left some distance beyond the flange 0 -to adapt it to reach Within the cavity h2 of the holder H. Surrounding this portion of the hub c is a coiled spring D which bears at one end against the flange b ofthe bushing B, and at the other against the flange c of the clutchmember C. Through this means the clutchmember C is maintained normally in engagement with the driving-pulley P by the action of the spring D. The clutch-member C is connected rotatively with the cone-holderl-l, while being free to slide axially -with respect thereto, through the arrangement next described: Referring to Figs. 1, 2 and 5, two lugs h4'. project rearwardly from the base of the holder H and enter opposite slots c4 cut through the outer rim c ofthe annular flange c on the hub of the clutch C. It will be noted from Fig. 2 that the rim c5 extends outwardly some distance beyond theportion' of the ange o formed with the beveled face 02 to adapt it to strike against the base end of the tube X to force the latter off yfrom the holder H after the teeth e2 of the arms e have been disengaged from its interior. 1

The clutch-member 'C is adapted to be slid on the bushing B to disengage it from thepulley P bymeans of an arm G pivotedl at g on an extension F fof the frame F and j reaching up to engage the side of the fiange c. The arm Gr forms a part ofthe automatic stopping-mechanism of the machine vto which is operated upon the breaking of the yarn or the exhaustion of the supply during ,the winding of a package or cone on the holder H. The arm G is also adapted to be operated from a hand-lever K to move the clutch-member to its extreme position to the left, as shown in Fig. 2to release ished cone'from the holder H. `The means for operating the arm G automatically forms the subject-matter of a separate application for patent and will not herein be described in detail; As `regards the present invention, suffice it to explain that the arm G is normally held' inactive in the position illustrated in Fig. 1 through detenta-means' arranged as next described, and is released by the/automatic4 devices not herein shown.

As illustrated inFig. 1 the arm Gr takes the form of a bell-crank-lever, havingua' horn-shaped extension g reaching toward the right with its end resting upon the top of a lug Z projecting from the hubA of a rocklever L. The lever L is pivoted on-a rod m extending at right-.angles to the axis of v the arm or lever Gr and held in bearings in the frame-extension F. Referring to Fig. 3, which is a view of the parts looking in the direction indicated by the arrow 3, Fig. 1, the lever L is' formed with a shoulder. or

shoulder 'n on a lever N. The lever N ispivoted on a cross-pin 0 arranged below .ledge Z adapted to vbe engaged by a detentand parallel with the pivot-rod m `of the lever L and serves as the prime element `for restraining the action of the clutch-releasmg means or for eifecting its operation whenthe automatic stop-devices come into play. The lever N is held normally balanced by a relatively light spring U, shown .in Fig. 1, to adapt its detent-shoulder n to engage the ledge Z on the lever L when I the latter is depressed. The spring U' is fastened at fn. to the lever N and at its upper end is hooked through a hole g2 in the arm g of the lever G. In this mannerthe spring U has the added function 'of maintaining the end of the arm g bearing .against the lug Z of the lever L. The lever L is operated to swing it upwardly bymeans of a spring V, see Fig. 1, fastened/,a-

toA a lug Z2 at the end of its arm Z8 and an-V chored to the frame F at f. A lug Z4 'on lthe upper side ofthe arm Zis adapted to strike to move the arm G to c rry the clutch-me/mber C out of'en'gagement with the pulley P,

but not enough to slide the clutch to release the .cop-tube X from Athe holder H. The purpose of this arrangement is to prevent the ejection of .the package from the holder H when the machine is stopped for piecing up the yarn or replenishiig its supply, *that is, before the package is completed, the

method of operation of the parts to secureA this end being moSre fully lexplained hereinafter.

Pivoted on the vsame rod g with thefarm G is the hand-lever K, previously referred to, which is formed with a' curved handle 7u reaching outI in convenient position below the cone-holder H. At its inner end the lever K is provided with two opposite abutments orfingers 7s', 702 which straddle the sides of the arm G to adapt the latter to be rocked in either direction from the movement of the handle 71:, while also allowing a slight play therebetween. Reaching back from the hub of the lever K is a curved arm the end of which normally lies above an arcuate extension or arch-member Z5 formed at right-angles to the main arm of the lever L, see Fig. 8. When the handlcver K is raised its arm 704 will be brought down against the top of thc arch-member 7"'7 to depress the lever L, and through this action the detent-ledge Z on said lever L is brought into engagement with the detentshoulder n on the lever N. In this way the handle 7c may be employed as a startinglever to eEect the operation of the machine after it has been stopped as more fully explained hereinafter. The method of operation of the complete apparatus is as follows:

The driving-pulley P is rotated continuously from a belt, not here shown, passing over its periphery and connected with any suitable source of power, and it is obvious that in place of the pulley P any other type of driving-member could be substituted, such as a gear or friction-wheel. When the machine is at rest the clutch-member-C is held free from the pulley P, in the position indicated by the dash-lines, Fig. l, by means of the arm G bearing against the side of the flange c. The pulley P thus runs free without driving the winding-mandrel or tube-holder H until the machine is prepared for operation as follows: The cone-tube or shell X is first forced snugly onto the holder H, as shown in Fig. l, and the spurs or prongs e2 on the arms e are caused to engage its interior through the'spring action of the said arms to secure the tube against accidental displacement. The end of the yarn to be wound into the cop or cone is then made fast to the tube X and inserted in the thread-guide, not here shown, which acts to traverse it on the tube in the usual manner during the operation of the machine. To start the machine the operator raises the handle of the lever K, thereby rocking the arm G to the right to free its end from the iange c on the clutch C to allow the latter to be forced into engagement with the pulley P by the action of its spring D. As the hand-lever K is raised as above described its extension or arm 704 is brought down against the top of the arch-member Z5 of the lever L and the latter will thereby be rocked against the action of its spring V. Referring to Fig. 3, this latter movement 0f the lever L carries its ledge Z down into position to be engaged by the shoulder n on the detent-lever N, this engagement being effected by the action of the spring U `on the lever N. The lever L will thus be locked in place against upward movement by its spring V and meanwhile the arm G is held free from the flange c of the clutch C by the action of the spring U, see Fig. 1. The clutch C will therefore be maintained in engagement with the pulley P under the aotion of its spring D, and hence the windingmandrel or tube-holder H connected with the clutch by its lugs 7L4 will be driven therefrom. The rotation of the holder H causes the yarn leading through the thread-guide to be wound onto the tube X to build it up in the conventional cone-shaped package or cop as usually employed in the art.

When the yarn breaks or its supply is eX- hausted the automatic stopping-devices which are connected t0 the detent-lever N act to rock said lever to release its shoulder n from the ledge Z on the lever L. This release of the lever L allows its spring V to rock it upwardly until its lug Z4 strikes against the cross-member f2 of the frame F. During this upward movement of the lever L its lug Z bears against the under side of the arm g of the lever Gr, see Fig. 3, and thereby rocks the latter to carry the end of its upright arm against the flange con the clutch C. This causes the clutch C to be slid to the left to disengage its beveled face c3 from the interior of the pulley P. As before stated, however, the limiting lug Z4 on the lever L is arranged to prevent the latter from moving the arm G to slide the clutch C to its full extent. That is to say, the movement of the arm G under action of 105 the lever L is just sufficient to yrelease the clutch C from the pulley P Without carrying the beveled face c2 of its ange c into engagement with the spring-arms or dogs e, see dash lines in Fig. l. It will therefore 110 be understood that the clutch C vis operated automatically to effect the stopping of the tube-holder or mandrel H without releasing the cop-tube from the holder.

When, however, the winding of the cone 115 or package has been completed and it is desired to remove it from the holder H this is accomplished by a manual operation as follows: The operator simply presses down on the handle 7c to rock the arm G farther 120 to the left, thereby carrying the flange c on the clutch C into engagement with the ends of the spring-arms e', as shown in Fig. 2. Continued pressure on the handle 7c causes the beveled face c2 of the flange c to act on 125 the inclined ends @-3 of the arms e to depress the latter and withdraw the teeth e2 radially inward to release them from the tube X. Meanwhile the rim c5 of the flange c comes against the end of the tube X and 130 sor the latter is forced free of the holder H to adapt the package to be easily doed therefrom. When another tube X is placed on the holder H, preparatory to winding a new package, the hand-lever K is released and the spring-arms e will be free to act automatically to allow the teeth e2 to make en- It will be observed that my improvement*v provides an extremely simple mechanism for performing the several operations necessary in preparing the machine for winding and Jfor starting or stopping its operation. The single hand-lever K serves not only for starting the machine but also acts as a means for dolin'g the cop or package and in this Way the manual control of the machine is rendered more convenient and its operation more elicient.
